LOSKINGDEVICE FOR SKYLIGHTS AND THE LIKE.

Application filed January 19, 1925. Serial No. 3,511.

7 '0 .aZZ whom it may concern Be it known that I, KARL RosnNHnIM, a citizen of the German Republic, and resident of Frankfort-on-the-liiain, Germany, have invented certain new and useful Improvements in and Relating to Locking Devices for Skylights and the like, of which the following is a specification.

My present invention relates to improve ments in looking devices for skylights and the like and has for its object to provide a new locking device of the type comprising a locking bolt adapted to be disengaged by a pull exerted on a handle-bar capable of being loosely engaged.

Locking devices heretofore known for skylights and adapted to be actuated by loosely engaged handlebars are generally objectionable in that the hooks of the handlebar may he accidentally disengaged or that the engagement between said hooks and the looking devices is a troublesome operation.

These objections will be completely avoided by the improved device hereinafter described, wherein the spring actuating the locking bolt may be grasped easily and readily by the widely open hook of the handlebar, accidental disengagement of the hook being at the same time securely prevented.

In the accompanying drawings I have illustrated one preferred form of my invention. In these drawings:

Fig. 1 shows the locking device secured onto a movable skylight.

Fig. 2 shows a, front elevation of the look ing device.

F 3 is a side elevation, and

Fig. l; is a top plan view thereof.

Arranged within the housing a is a locking bolt"b,which is urged by the upper arm of the U-shaped wire-spring 0 upwardly to its locking position, said upper arm of the spring being freely movable in the slots a of the housing a. The lower arm of said spring 0 is attached in the housing a in such a way that it clears the locking bolt 7) and cannot be engaged by the same, and to this end said locking bolt is provided with a slot Z). The closed end of the U-shaped spring 0 projects outwardly from the housing to such extent that the upper arm of said spring may be easily grasped-by the hook d oi": the pulling bar, said closed end of the spring being fastened by an eye-bolt or the like as shown, so that it cannot be pulled downwardly. The U-shape of the spring 0 permits of the fixed end of the spring being attached within'the housing of the bolt, but it will be understood that any other shape of spring may also be used.

In close proximity to the guide-way for the bolt, the housing a has a roof-shaped proectmg striking square. The passage of the hook cl between the spring 0 and said roof is not larger than the thickness of said hook. N ow if the pulling bar, after having grasped the spring 0 by the hook (Z, is moved towards the locking-bolt below the projecting square, the accidental disengagement of said bar will be made impossible as shown in Fig. 3.

The widely open hook will be engaged at the top and become as safe as a completely closed eye. i

Having now fully described my said in vention, what I claim and desire to secure by Letters Patent, is:

1. In a locking device for skylights and i the like,a housing, a locking bolt slidably mounted thereln, a spring for normally holding the bolt in looking position, an operating handle having an open book to engage the spring, the spring being extended beyond the housing to permit the free engagement of the open hook with said spring, the housing being formed with means to prevent the separation of the hook and spring when the former has been moved to spring operating position within the housing.

2. In a locking device for skylights, a housing, a locking bolt slidable therein, a U- s iaped spring having one terminal fixed relative to the housing and the opposite termi nal cooperating with the bolt, the U-shaped spring being extended beyond the housing, and an operating member having an open hook freely engageable with and disengageable from the bolt engaging portion of the spring beyond the housing, said housing having means disposed in such relation to the bolt engaging portion of the spring as to prevent disengagement of the open book from said spring when the hook has been moved to a position within the housing for the operation of the bolt.

8. In a locking device oi the character described, a housing, a bolt slidable therein, a U-shaped spring having one leg fixed with relation to the housing and the other leg engaging the bolt, said spring being extended beyond the housing, and a wall carried by the housing and overlying and defining a lli) predetermined space relative to the operative leg of the spring.

4:. In a locking device of the class described, a plate formed at one end to provide a bolt receiving housing, a bolt slidahle in said housing, oneedge ot the platebeyond the housing being formed with a flange ex tending from the housing, and a U-shaped spring having a fixed leg passing through aligned openings in the housing and through a slot in the bolt and. its operative leg passing through slots in the housing and an openingin the bolt, the active leg of the spring being arranged; in predetermined spaced relation from the said flange, and the spring as a Whole extended beyond the end of the plate remote from the bolt.

In testimony whereof I have hereunto set my hand.
